局所膝関節冷却の時間短縮が膝伸展トルクに与える影響

Abstract

[Purpose] To clarify the effect of shortening the Focal Knee Joint Cooling (FKJC) time on knee extension torque under three conditions: no cooling, 15-min FKJC, and 30-min FKJC. [Participants and Methods] Knee extension torque was measured over time in 18 healthy adult male subjects after three cooling conditions : no cooling, 15-min FKJC, and 30-min FKJC. [Results] Isometric knee extension torque was greater in the cooling groups than in the no cooling group. Twenty minutes after the measurement, the cooling groups showed a significant difference compared to the no cooling group. [Conclusion] Isometric knee extension torque showed an immediate cooling effect even when FKJC time was reduced from 30 to 15 min. Therefore, 15-min FKJC followed by 20 min of physiotherapy aimed at increasing knee extension may help prevent falls.
